when we want to add license server, it not allow where duplicate MAC address is being registered
any method to delete register MAC address from account A ? so that we can register to account B

Open a ticket with ESP (Enterprise Support).


is it possible to move an NVIDIA license server from a 2008R2 virtual server to a 2019 virtual server?

You can simply return the licenses on the vGPU portal and issue a new license file for the new license server.
